  • Two novel calixarene-based fluoroionophores were synthesized. Their conformations were confirmed to 1,3-alternate by X-ray crystal structures. From CHEF by blocking the PET mechanism in fluorescence spectra, we observed $In^{3+}$ and $Pb^{2+}$ selectivity over other metal ions. For $In^{3+}$ion, calix[4]-bis-azacrown-5 showed about 20 times more sensitive than calix[4]-mono-azacrown-5 because the source of the binding selectivity comes from the calixarene framework and azacrown ligand by controlling the fluorescence and PET mechanisms as-sociated with the amine moiety.

  • For the efficient operation of container terminals, it is essential to develop optimal operation rules for marshaling yard and yard cranes. However, derision rules for conventional container terminals expose various limitations to be applied to automated container terminals. This paper introduces a development of a simulation model for evaluating various operation rules for automated transfer cranes (ATCs) and yard operation in the marshaling yard.
